CD276/B7-H3 Polyclonal Antibody Sizes: 50µl, 100µl Catalogue Numbers: BS78241-50, BS78241-100 Product: 1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2 Swiss-Prot: Q5ZPR3 Host: Rabbit Reactivity: Human Applications: WB All Applications: WB,1:500 - 1:2000 Background: The protein encoded by this gene belongs to the immunoglobulin superfamily, and thought to participate in the regulation of T-cell-mediated immune response. Studies show that while the transcript of this gene is ubiquitously expressed in normal tissues and solid tumors, the protein is preferentially expressed only in tumor tissues. Additionally, it was observed that the 3' UTR of this transcript contains a target site for miR29 microRNA, and there is an inverse correlation between the expression of this protein and miR29 levels, suggesting regulation of expression of this gene product by miR29. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
